#1 - Took the Heroine's First Time
There are three elements you can't leave out of a modern novel.
Regression, possession, reincarnation.
Commonly known as the holy trinity of modern Korean webnovels—regression, possession, and reincarnation. You absolutely can't skip these in a Korean-style story.
These elements offer the most direct sense of liberation to ordinary people living mundane lives...
But if you actually become the subject yourself, you won't find it funny at all.
No liberation or anything like that—just a bleak future ahead.
To cut to the chase: yeah. I got possessed.
Into the romance fantasy novel Aria of Radiance.
The plot of Aria of Radiance is simple. A girl named Viola living as a nun in a rural village gets chosen as a saintess, gets entangled with the male leads, and they all defeat the demon king together. A textbook female-oriented romance fantasy.
Yeah, fine. Getting possessed? Not bad so far.
So what's the problem? Simple.
...I didn't become one of the male leads. I didn't even get gender-bent into Viola. No, I became the final boss, Demetrius de Belpert.
Yeah, that Demetrius de Belpert—the demon king and incubus final boss who gets surrounded by the male leads and heroine, hit with a line like "How pitiful, you who never knew the beauty of love," and then slain.
At least there's one silver lining: this Demetrius de Belpert wasn't the demon king yet.
To be precise, I got possessed right in the middle of the war for the demon king's throne.
So what did I do?
My brilliant mind made a snap decision.
Even if I struggled to become demon king, I'd just get killed anyway. So I ran away.
A brilliant call. And with that brilliant decision, I successfully escaped under the cover of night. A perfect fit for the term "midnight flight."
Fortunately, I could fly around with my demon wings and cast magic like it was second nature, as if I'd always been able to. I don't know who shoved me into this body, but thanks for that much.
Anyway, after fleeing that demon king scramble...
"Priest niiim♡"
"Everyone, didn't I tell you not to run inside the church?"
...I ended up as the priest in this peaceful rural human village.
You might wonder how the hell that happened, but the moment you start questioning it, you've already lost.
Honestly, I have no idea myself how it came to this.
After barely escaping the Demon Realm, I crossed into the human world and spotted a rural village.
The kind of place that screams "peaceful."
I figured I'd hide out nearby, assess the situation, and plan my next move...
"Wh-who... are you...?"
Of course, I got spotted by some old lady passing by.
What should I say? While I was pondering and quickly hiding my tail and wings, she thankfully had bad eyesight and didn't notice them.
No, it was more than that.
"...Are you the new priest who was supposed to be dispatched here?"
She mistook me for a priest.
"Y-yes...? No, I'm not a prie—"
"Aigoo, how could a fine young man from a noble house...?"
"Uh... yes...?"
The old lady barreled ahead on her own narrative and dragged me straight to the village church.
By then, every eye in the village was on us, so I got half-forced into becoming this church's priest.
*
About two months passed like that.
Bottom line: this life? Incredibly comfortable.
Sure, not having 21st-century conveniences was annoying, but magic filled in for a lot of it, and as an incubus, I didn't need to eat much anyway.
Priest duties were a breeze—just follow the records left in the church, and it worked fine. The place didn't have much to do in the first place.
Aside from a few minor inconveniences, I was actually pretty satisfied with my days.
I thought today would be another ordinary day of work and basking in the peace.
Today was one of the rare days for watching the village kids, so I was tending to them when, around evening, I sensed someone approaching the church.
The kids playing in the yard got all rowdy, so it must be someone familiar.
The lady from the house down the road coming to vent her worries? Or the hunter uncle here to brag about his exploits?
Either way, I planned to use the kids as a shield to dodge it and dump the hassle on future me...
"Excuse me...?"
...Out came a woman you’d never expect to see in a backwater rural village like this.
Light purple hair so pale it almost looked white, a figure with curves in all the right places, purple eyes matching her hair, a gentle smile, and a soft, clear voice.
It had been so long since I’d seen a woman like this. First time seeing her in person, actually.
"Huh...? You're not what I heard... um..."
She stepped inside, glanced around the church, spotted me, and slowly walked over.
I just stared at her blankly the whole time.
Two reasons.
First, I knew who she was, and it stunned me.
Her name was Viola.
The heroine of this world I’d possessed into—the woman who would kill me in the future if I became the demon king.
No way I wouldn’t freak out seeing someone who could kill me at any moment.
Second... yeah, let’s just say it.
She was fucking gorgeous.
Even from my perspective, having seen countless women in the 21st century with all their filters and enhancements, her beauty was shockingly stunning.
And on top of that stunning face, my incubus instincts were stirring up lust stronger than ever before.
The only reason I held back was because I was acutely aware she could kill me.
While I was frozen like an idiot, Viola approached me.
"Um, are you this village's priest...?"
"Uh... ah, yes. I'm the priest of this village, Kasian."
Kasian was a name I made up on the spot.
Demetrius de Belpert was too long, too complicated, and didn’t sound normal at all.
"I thought there was no priest in this village..."
How should I spin this to make her buy it? As I racked my brain, Viola helpfully provided my excuse.
"...Oh, did one of the villagers step in temporarily?"
"Ah... uh, yes. That's right. Haha..."
"I see...! I'm so sorry, and thank you for looking after everyone in the Holy Kingdom's place!"
Viola bowed politely, the picture of perfect manners.
I caught her scent wafting from her.
Sweet, fragrant—enough to muddle my mind.
"Ah, I forgot to introduce myself...! I'm Viola! A new nun dispatched from the Holy Kingdom!"
Info swirled in my head. What should I say? How should I act?
My head hurt like hell, but our kind Viola kept the conversation going.
"If it's okay with you, could you keep serving as priest here? This is my first dispatch, and I don't know much about this rural area. I'll handle things with the Holy Kingdom for you!"
"Ah... uh, yes...."
"Is that alright...? Um, does your head hurt...?"
The moment she reached out, I shoved her away roughly.
Dangerous. The closer she got, the harder it was to keep my reason intact.
I dodged her touch and shook my head.
"Ahh, I'm fine. Yes, I'm fine. Really."
Yeah, I'm fine. Totally fine. So please don't touch me. For my sake. For hers.
"...Let me show you to your room."
I led her to the hut next to the one I'd cleaned for myself behind the church.
"...I'll handle the cleaning."
"Ah, no...! There were kids around earlier—I'll do it!"
"......Please do."
I left the cleaning to Viola and put distance between us.
Once away from her, it got better. My muddled mind started clearing up.
What now? Midnight flight again? Or some other way?
While thinking it over, I took the kids home and tidied the church.
My decision was simple.
Midnight flight.
Better to eliminate the risk.
It was a shame. These two months had been so comfy, and the villagers were all kind and simple folk.
So deep in the night, I snuck out of my hut...
“Priest♡ Priest♡ Priest♡ Ahh♡ Ahn♡ Nngh♡ Ah♡ Aaang♡”
“Haaaah♡♡♡♡♡♡♡♡♡♡”

...How the hell did this happen?
